Worked example: 150 mcg
- Convert the vial amount to mcg: 5 mg × 1,000 = 5,000 mcg
- Concentration: 5,000 mcg ÷ 3 mL = 1,666.67 mcg/mL (1.66667 mg/mL)
- Volume to draw: 150 mcg ÷ 1,666.67 mcg/mL = 0.09 mL
- Units to draw: 0.09 mL × 100 units/mL = 9 units
- Amount in each unit: 1,666.67 mcg/mL ÷ 100 units/mL = 16.67 mcg per unit (0.01667 mg)
- Doses in the vial: 5,000 mcg ÷ 150 mcg = 33 full doses
Draw 9 units on a U-100 syringe, halfway between the 8- and 10-unit marks. The same 150 mcg dose is 7.5 units with 2.5 mL of water and 15 units with 5 mL of water, compared with 9 units with 3 mL.
Frequently asked questions
What is the concentration of a 5 mg vial with 3 mL of water?
A 5 mg vial mixed with 3 mL of water holds 1,666.67 mcg per mL. Each unit on a U-100 syringe holds 16.67 mcg.
How many units is 150 mcg with a 5 mg vial and 3 mL of water?
It is 9 units on a U-100 syringe, which is 0.09 mL of the mixed liquid.
What is the smallest dose you can measure well with a 5 mg vial and 3 mL of water?
About 33.33 mcg, which fills 2 units on a U-100 syringe. Smaller amounts are hard to read; a vial mixed with more water spreads them over more units.
What is the largest dose that fits a 1 mL syringe with a 5 mg vial and 3 mL of water?
1,666.67 mcg, which fills all 100 units of a 1 mL U-100 syringe. Larger doses need more than one draw or a stronger mix.
How many doses does a 5 mg vial with 3 mL of water give?
Divide 5,000 mcg by your dose and round down: 33 full doses of 150 mcg, or 25 of 200 mcg.
